目前,磨床砂轮使用前的平衡通常都是在砂轮平衡架上完成的。这种方法既费时,又费力。此外,平衡的质量完全取决于工人的主观判断,常因砂轮平衡不良而影响被磨削工件的表面粗糙度。 近年来,我们应用“三点平衡法”对砂轮进行平衡,取得了较好的效果。 一、做法“三点平衡法”的基本过程:首先测量 旋转体不平衡引起的振动量;然后,在需要实施配重的圆周上确定相位相差120°的三点,在其上分别加试验配重后,测量各自新的不平衡振动量,最后通过作图找出需加真实配重的位置和
At present, the balance of grinding wheel before use is usually done on the wheel balancer. This method is time consuming and laborious. In addition, the balance of quality depends entirely on the subjective judgment of workers, often due to bad balance wheel affected the workpiece surface roughness. In recent years, we use the “three balance method” to balance the wheel, and achieved good results. First, the practice of “three-point balance method,” the basic process: First, measure the amount of vibration caused by the imbalance of rotating body; and then, in the need to implement the counterweight on the circumference of the phase difference of 120 ° to determine the three points, respectively, After weighing, measuring their new imbalance vibration, and finally through the mapping to find out the location of the need to add real weight and
